General N=(1,1) dilaton supergravity in two dimensions allows a background independent exact quantization of the geometric part, if these theories are formulated as specific graded Poisson-sigma models. In this work the extension of earlier results to models with non-minimally coupled matter is presented. In particular, the modifications of the constraint algebra due to non-minimal couplings are calculated and it is shown that quartic ghost-terms do not arise. Consequently the path-integral quantization as known from bosonic theories and supergravity with minimally coupled matter can be taken over.
